I'm a TTS 6uk with 25cm foot length. I followed the adidas size chart and went for 7uk. However, this style comes up big for my standard width feet. A 6.5 uk would be perfect without looking long and having heel spilage. I love the shoe, quality is amazing but the sizing is off. Im sure 1/2 a size up your normal size will be great since the leather stretches after a few wears. Can't comment about comfort because I only tried them inside the house. Also try loosening the laces if it feels too tight.

Top notch … very comfy and good product . I will recommend it for anyone
